> There is no address which can be reached from the internet Maybe read my previous [1] again? If you are behind a NAT only - which would be highly unusual - you probably can send packets to it from the internet. The router will simply forward packets that have an internal (RFC 1918) DST address. That only thing NAT does is rewrite address fields. The reason you usually cannot receive packets directly from the internet is due to the stateful firewall. > "If my machine does not have a direct Internet address, due to NAT configuration, am I safe from ME exploits"? s/NAT/firewall/
